Again returns the nutrients from human urine by using the patent pending additive ZeopeatTM. In the process, which happens by mineralisation and ion-exchange, phosphorus, nitrogen, potassium and different micronutrients are captured. The end result is the concentrated fertiliser gainutriTM. Starting from separated urine, fully 98% of the phosphorus and 70% of the nitrogen and potassium is captured. Proof of what Again is working for – a closed nutritient cycle!
The photo shows the reactor made by Again installed at the Ekocentrum environment center in Gothenburg.
In larger plants, such as biogas reactors, up to 90% of the nitrogen from the plant’s reject water is captured and mixed with peat, a process which leads to the production of Again’s own nutrient enriched cultivation soil, nymylla. The additive ZeopeatTM, can also be mixed with separated urine from dry toilets such as an ongoing project in Bolivia.
The animation below shows the principle of how Again returns the nutrients using the patented additive ZeoPeatTM.
NB! returineTM is now replaced by gainutriTM
